the second has also a few large ones ; elsewhere the punctures 

 are much smaller, dense on the fifth, and sparse on the third 

 and fourth. The three typical specimens are apparently all 

 somewhat abraded. On the prothorax the scales axe rather 

 elongate, and each is set in a puncture, some of them are sooty, 

 but the majority are fawn-coloured ; on the elytra the scales 

 in the punctures are decidedly smaller, but otherwise similar 

 to those on the prothorax ; but on the interstices such scales 

 as are left are more or less circular, and vary from almost 

 white to sooty. On the under-surface the scales are usually 

 longer and paler, and on the legs and head denser, than 

 elsewhere. 



Decilaus mirabilis, n. sp. 



Deep shining-black, tip of prothorax and tibise diluted 

 with red ; antennae, tarsi, and apical segment of abdomen paler. 

 Almost entirely glabrous. 



Head with a few large punctures in front. Rostrum stout, 

 sides lightly incurved to middle, with a strong median carina 

 and two smaller sublateral ones, all three continued almost to 

 apex ; with a row of strong punctures between each two carinse. 

 Antennae rather thin, inserted about one-third from apex of 

 rostrum ; scape about the length of five following joints ; club 

 rather large. Prothorax strongly transverse, sides strongly 

 rounded; with large, round punctures. Elytra subcordate, 

 base truncate, sides strongly rounded and widest at about basal 

 third ; with rows of large punctures, in moderate striae ; inter- 

 stices wider than striae, with fine punctures and minute 

 wrinkles. Mesosternal receptacle like portion of an elevated 

 ring. A hdomen with two basal segments no longer than third 

 and fourth, fifth almost as long as four basal ones combined, 

 with a rather large but shallow median fovea. Femora rather 

 long, strongly grooved ; front tibiae lightly dilated from base 

 to apex, the others narrowest at apex and subangularly dilated 

 near base. Length, 1-| mm. 



Hah. — Queensland: Mount Tambourine, in rotting leaves 

 (A. M. Lea). Type, I. 1327. 



A minute black species, with unusually coarse sculpture. 

 It may be necessary later on to refer it to a new genus. Under 

 a. Coddington lens the apical segment appears to be half the 

 total length of the abdomen ; the first and second are unusually 

 short, irregularly concave, and on the type the suture between 

 them cannot be traced, so that the abdomen appears to consist 

 of but four segments only. 



Decilaus tkivirgatus, n. sp. 

 Of a dingy-castaneous, under-surface darker, elytra more 

 or less deeply stained with black on suture and sides. Sparsely
